This paper describes and evaluates a compiler transformation that improves the performance of parallel programs on Network-of-Workstation (NOW) shared-memory multiprocessors. The transformation overlaps the communication time resulting form non-local memory accesses with the computation time in parallel loops to effectively hide the latency of the remote(More)
Cardiac pacemaker cells autonomously generate electrical impulses that initiate and maintain the rhythmic contraction of the heart. Although the majority of heart cells are thought to originate from the primary and secondary heart fields, we found that chick pacemaker cells arise from a discrete region of mesoderm outside of these fields. Shortly after(More)
Protein carbamylation is a post-translational modification that can occur in the presence of urea. In solution, urea is in equilibrium with ammonium cyanate, and carbamylation occurs when cyanate ions react with the amino groups of lysines, arginines, protein N-termini, as well as sulfhydryl groups of cysteines. The concentration of urea is elevated in the(More)
This thesis describes a novel approach for distributing low skew clock signals across large digital systems independent of environmental and process variations. The technique is integrated into a multi-output clock buffer circuit that can handle a scalable number of clock loads in a point-to-point configuration. The circuit contains an impedance-locked loop(More)
Developing suitable processes for thin wafer fast recovery power diodes is important for modern production plants as the substrate dimension increases. A set of emerging technologies has been employed here in order to fabricate 1700V rated fast recovery diodes from standard Si IGBT substrates without pre-diffused backside n-type buffer. Wafer grinding,(More)
A recent ar)cle in HPCWire recognizes ORNL's Scalable Heterogeneous Compu)ng benchmarks, which are sponsored by DOE ASCR and NSF, for performance tes)ng on emerging architectures with OpenCL and CUDA. Kyle Spafford from ORNL's Future Technologies group has been benchmarking the two technologies for some)me and is now convinced that OpenCL performance is(More)
